ERNEST WILLIAM BATTEN, OF HERNE HILL, LONDON, ENGLAND.

AUTOMATIC PNEUMATIC MUSICAL INSTRUMENT.

To all whom it may concern:

Be it known that I, ERNEST VVILLIAM BATTEN, a subject of the King ofGreat Britain, and residing at Herne Hill. London, S. E., England, haveinvented certain new and useful Improvements in Automatic PneumaticMusical Instruments, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

This invention relates to what are known as automatic musicalinstruments which employ a perforated roll or sheet of music, and theinvention consists of the employment of a magnifying glass or lens,placed in such position that the player by its assistance can moreeasily read or follow the course of the music-roll ,while the music isbeing rendered.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a front elevation of aninstrument involving my invention, and Fig. 2 a sectional side elevationof that portion of the instrument to which my improvement is applied.

In Fig. 1, A indicates the roll of music; B, the magnifying glasscontained in a frame (preferably of metal); C, the metal arm-piece orbracket, holding glass in position; D, a screw, by means of which theposition of the glass can be varied.

In Fig. 2, A indicates the roll of music; B, the magnifying glass,contained in a frame, (preferably of metal) C, the metal arm-piece orbracket holding glass in position; D, a small screw by means of whichthe position of glass can be varied. The bracket is rotatably supportedat E thus enabling it to be swung aside when musicroll is either placedin or taken from instrument. F indicates a sliding glass panel, used insome instruments (imperatively those worked by pressure neumatics) anddrawn across front of music-recess after music-roll is in position. Itspurpose has no interest or bearing upon the device herein described. Bymeans of this construc- Specification of Letters Patent.

tion the glass holder may be swung freely in a plane parallel of and infront of the rotary support for the roll or sheet of music and saidframe may also be adjusted in said plane, this last operation beingaccomplished by means of the set screw D.

Irrelevant details have purposely been omitted, and only enough shown indrawing, to illustrate this specification.

Any suitable and convenient method of mounting or placing the glass inits position, may be adapted and each instrument must be so dealt within this respect as to secure the greatest convenience and efficiency; noclaim whatever being made in this direction.

The invention is useful where any class of roll is used, but especiallyis its value apparent when, in some of the later instruments, rolls ofmusic are employed containing very small markings and perforations.

Moreover, as the correct tracking or passage of the roll in someinstruments, is under the control of the player, the skilfulmanipulation of which is imperative to the correct rendering of theselection being played, the value of a means of doing this easily, it atonce apparent.

A glass of any power may be employed, but experience points to theadvisability of using one of moderate strength; as any distortion thatotherwise may possibly arise, is thus entirely overcome.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. An attachment for an automatic musical instrument having a rotarysupport for a perforated roll of sheet music, comprising a holderadapted to be secured above said support, a bracket rotatably connectedwith said holder and a frame connected with said bracket and providedwith a magnifying glass or lens, said frame, when said attachment is inposition, being vertically adjustable and adapted to swing in a planeparallel with said support.

2. The combination with an automatic musical instrument having a rotarysupport for a perforated roll of sheet music, of an attachmentcomprising a holder secured above said support, a bracket rotatablyconnected With said holder and a frame conpresence of the subscribingWitnesses this nected with said bracket and provided with 15th day ofMarch 1909.
